The dosage chart on the label is a recommendation by GNC Scientists for the best results from 100% Soy Isolate. It is recommended that the minimum daily dose is taken on each day based on activity level.

Pro Performance® 100% Soy Isolate is a protein shake that is cholesterol-free, with no lactose, and is from vegetarian sources. Soy protein is one of the most anabolic proteins. One of the biggest misconceptions behind this protein is the link to estrogen production; however, it contains all of the essential amino acids, including BCAA. BCAA may help preserve muscle glycogen stores and reduce the amount of protein breakdown during exercise. This formula features Supro® soy protein, one of the most clinically studied so proteins. Supro® is made from soybeans that are produced while being tightly monitored and controlled from planting through processing.

The Pro Performance® Results AdvantageProtein is an essential nutrient that is necessary for the growth, repair and maintenance of body tissues such as skin, bones and muscles. Studies have shown that soy protein taken by active individuals helps support muscles during exercise. Additionally, diets low in saturated fat and cholesterol that include 25g of soy protein a day my reduce the risk of heart disease.

One serving of Pro Performance® 100% Soy Isolate features 25g of protein providing an equivalent nitrogen factor of 25. Soy Protein is an effective source of nitrogen for fueling lean muscle mass. Your muscles can only grow when your body retains enough nitrogen. This formula delivers naturally-occurring anabolic amino acids into your bloodstream. This spike in aminos provides nitrogen and subsequently creates a nitrogen-rich environment needed for maximum muscle protein synthesis. Protein synthesis is crucial to the building of lean muscle mass.

The Pro Performance® Quality AdvantageGNC Pro Performance® 100% Soy Isolate is also tested for banned substances,* providing peace of mind in the highest quality formulation. Our researchers created a superior formula that not only delivers muscle fueling results, but every flavor has a satisfying, delicious taste profile. Each serving mixes up instantly with a blender, shaker, or a spoon- It’s that smooth and it couldn’t be easier.

Health Notes

Disclaimer:
This scientific independent research is provided by Aisle7 and is for informational use only. GNC provides this information as a service but does not endorse it. Likewise, Aisle7 does not recommend or endorse any specific products.

For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

This supplement has been used in connection with the following health conditions:

Dose: 33 to 40 grams dailyIn one study, elderly men participating in a strength training program who took a supplement containing protein (part of which was soy protein) immediately following exercise saw significant gains in muscle growth and lean body mass.(more)

Soy supplementation has been shown to lower cholesterol in humans.1 Soy is available in foods such as tofu, miso, and tempeh and as a supplemental protein powder. Soy contains isoflavones, naturally occurring plant components that are believed to be soy's main cholesterol-lowering ingredients. A controlled trial showed that soy preparations containing high amounts of isoflavones effectively lowered total cholesterol and LDL ("bad") cholesterol, whereas low-isoflavone preparations (less than 27 mg per day) did not.2 However, supplementation with either soy3 or non-soy isoflavones (from red clover)4 in pill form failed to reduce cholesterol levels in a group of healthy volunteers, suggesting that isoflavone may not be responsible for the cholesterol-lowering effects of soy. Further trials of isoflavone supplements in people with elevated cholesterol, are needed to resolve these conflicting results. In a study of people with high cholesterol levels, a soy preparation that contained soy protein, soy fiber, and soy phospholipids lowered cholesterol levels more effectively than isolated soy protein.5

In a double-blind study of postmenopausal women, supplementing with 10 grams of soy protein twice a day for six weeks significantly reduced diastolic blood pressure by an average of 5 mm Hg, compared with a diet not containing soy protein.1 In another study, men and women with mild to moderate hypertension consumed 500 ml (approximately 16 ounces) of soy milk or cow's milk twice a day for three months. After three months, the average systolic blood pressure had decreased by 18.4 mm Hg in the soy group, compared with 1.4 mm Hg in the cow's milk group. The reductions in diastolic blood pressure were 15.9 mm Hg with soy milk and 3.7 mm Hg with cow's milk.2 In another study of people with hypertension who were consuming a low-protein, low-fiber diet, supplementing with a combination of soy protein and psyllium (a fiber source) lowered systolic blood pressure by an average of 5.9 mm Hg.3 The blood pressure reduction with soy protein alone or with fiber alone was less pronounced than that with combination treatment. Other research has also shown a blood pressure-lowering effect of soy protein.4, 5

In a double-blind trial, supplementing with soy protein (providing 68 mg of isoflavones per day) for two menstrual cycles was significantly more effective than a placebo at relieving premenstrual swelling and cramping.1 The placebo used in this study was cow's milk protein. Some doctors believe that cow's milk, because of its estrogen content, can worsen premenstrual symptoms. If that is the case, then the beneficial effect of soy protein may have been overestimated in this study.

A double-blind study of 78 postmenopausal women (average age, 49.5 years) were randomly assigned to receive 60 mg per day of soy isoflavones (as aglycone) or placebo for six months.1 Then after a one-month break, each woman received the alternate treatment for an additional six months. Thinking (cognitive) performance and mood were assessed by tests at the end of each treatment period. Compared with placebo, people treated with isoflavones experienced significant improvement on 6 of 17 measures of cognitive function and 7 of 8 measures of mood. In another double-blind study, 177 postmenopausal women (average age, 55 years) who were experiencing five or more hot flushes per day were randomly assigned to receive soy isoflavones (50 mg per day total of an approximately equal mixture of isoflavones genistin and daidzin) or placebo for 12 weeks.2 The average reduction in hot flash frequency after 6 weeks was significantly greater in the isoflavone group than in the placebo group; however, during the entire 12 weeks, the difference between the two groups was only marginally significant.

Dose: Refer to label instructionsAnimal and human studies have suggested that when soy is used as a source of dietary protein, it may have several biological effects on the body that might help with weight loss.1 A preliminary study found that people trying to lose weight using a meal-replacement formula containing soy protein lost more weight than a group not using any formula.2 However, controlled studies comparing soy protein with other protein sources in weight-loss diets have not found any advantage of soy.3, 4, 5 When soy protein is used for other health benefits, typical daily intake is 20 grams per day or more.

In one preliminary study, elderly men participating in a 12-week strength training program took a liquid supplement containing 10 grams of protein (part of which was soy protein), 7 grams of carbohydrate, and 3 grams of fat either immediately following exercise or two hours later.1 Men taking the supplement immediately following exercise experienced significantly greater gains in muscle growth and lean body mass than those supplementing two hours later, but strength gains were no different between the two groups. A controlled study of female gymnasts found that adding 0.45 grams of soy protein (0.45 grams per pound of body weight per day) to a diet that was adequate in protein during a four-month training program did not improve lean body mass compared with a placebo.2 No research has compared different sources of protein to see whether one source, such as soy protein, has a better or more consistent effect on exercise recovery or the results of strength training.
